However, he soon found himself summoned to another world by an evil wizard, who had him possess the body of a boy as an experiment. After successfully planning the evil wizard's downfall, he used the wizard's body as a springboard to gain influence and power in his new world.
The Wilder Plain was covered by six foot tall grass. Whenever the wind was strong enough to part it, it would reveal thousands of boarbeasts. These animals were native to the Wilder Plain, and was the food source for most carnivores living there. Boarbeasts were very mild in nature, and rarely attack other animals. Whenever they were attacked, they tended to run instead of fighting back. They were herbivores, and reproduced very fast to prevent extinction. If there were no boarbeasts, the other beasts would starve to death. If there were no other beasts, the boarbeasts would destroy the plain.
